progress of a nation

I just read this in a review of Paul Krugman's new book, The Conscience of a Liberal. I thought it was worth repeating.

He recites the now-familiar data that the wealthiest 0.01 percent of Americans are seven times richer than they were three decades ago, while the inflation-adjusted income of most American households has barely nudged upward. Chief executives who typically earned 30 times more than their average employee in the 1970s now take home more than 300 times as much.
